Method: BufferedTokenStream#adjustSeekIndex

Defined in:
lib/antlr4/BufferedTokenStream.rb

#adjustSeekIndex(i) ⇒ Object

Allowed derived classes to modify the behavior of operations which change the current stream position by adjusting the target token index of a seek operation. The default implementation simply returns i. If an exception is thrown in this method, the current stream index should not be changed.

<p>For example, CommonTokenStream overrides this method to ensure that the seek target is always an on-channel token.</p>

Parameters:

  • i —

    The target token index.

Returns:

  • The adjusted target token index.
